Add tests for the `block-tracker-inspector` middleware — which makes
sure that the block tracker never has a reference to the latest block
which is less than a block number that shows up in an RPC method's
response — and the Infura middleware — which takes care of sending the
request to Infura, and will retry the request up to 5 times if Infura
sends back a certain type of error.
Note that the `retry-on-empty` middleware is not tested because it
currently has a [bug][1] which is making it ineffective.

* Upgrade style from Enzyme to React Testing Library
* Use real i18n provider instead of a fake one so that we can look for
English text instead of just i18n strings, improving readability
* Swaps: Show a network name dynamically in a tooltip
* Replace “Ethereum” with “$1”, change “Test” to “Testnet”
* Replace 이더리움 with $1
* Translate network names, use ‘Ethereum’ by default if a translation is not available yet
* Reorder messages to resolve ESLint issues
* Add a snapshot test for the FeeCard component, increase Jest threshold
* Enable snapshot testing into external .snap files in ESLint
* Add the “networkNameEthereum” key in ko/messages.json, remove default “Ethereum” value
* Throw an error if chain ID is not supported by the Swaps feature
* Use string literals when calling the `t` fn,
* Watch Jest tests silently (no React warnings in terminal, only errors)
* Add @testing-library/jest-dom, import it before running Jest tests
* Add snapshot testing of Swaps’ React components for happy paths, increase minimum threshold for Jest
* Add the test/jest folder for Jest setup and shared functions, use it in Swaps Jest tests
* Fix ESLint issues, update linting config
* Enable ESLint for .snap files (Jest snapshots), throw an error if a snapshot is bigger than 50 lines
* Don’t run lint:fix for .snap files
* Move `createProps` outside of `describe` blocks, move store creation inside tests
* Use translations instead of keys, update a rendering function to load translations
* Make sure all Jest snapshots are shorter than 50 lines (default limit)
* Add / update props for Swaps tests
* Fix React warnings when running tests for Swaps
